Ruby on Rails:使用"rails生成控制器欢迎“时权限被拒绝
提问于 2014-05-23 14:35:11
我在Red Hat服务器上使用Ruby on Rails。当我试图生成一个控制器文件时，我得到了这个错误：
[ec2-user@ip-172-31-22-128 testApp4]$ rails generate controller welcome

我通过运行以下命令解决了这个问题
sudo chmod -R 1777 /tmp我希望这对像我这样不想停用弹簧宝石的人有所帮助

它需要所有权来为每次服务器启动写入重写pid。
我必须用我的完整本地路径& sudo来运行它
$ sudo chmod /Users/MyName/Desktop/projects/my_project/tmp/ -R 777

我查看了试图写入pid文件的库lib/spring/env.rb。
除非设置了XDG_RUNTIME_DIR，否则该函数每次都会尝试在同一位置创建一个临时目录：
path = Pathname.new(File.join(ENV['XDG_RUNTIME_DIR'] || Dir.tmpdir, "spring"))
将所述变量设置为唯一的目录对我来说是可行的：
